#Function-N#

A java 8 functional extension.

This "extension" provides extra function objects that the java.util.function package does not offer. You can find java.util.function.Function and java.util.function.BiFunction but there is nothing for functions that accept 3 arguments or more. With the Function-N extension you can have functions that accept 1 argument to functions that accept 8.

##Function composition##

You can compose functions of N with functions of M to get functions of N + M - 1. For example, a Function3 composed with a Function4 returns a Function6.

##Function currying##

You can partially apply a function of N by supplying it with some value and receive a function of N - 1. Each function of N provides a curry function to do so. For example

Function2<Integer, Integer, Integer> add = (x, y) -> x + y;
Function<Integer, Integer> addc = add.curry(5);
System.out.println( addc.apply( 4 ) ); // prints 9

##Extendible##

Function-N supports up to 8 functions but you can easily extends the function generator to produce 16, 32, 64, ... function objects!
